To all whom it may concern: 7 Be it known thatI, MARTIN L. RAHNER,

' a citizen of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Bubbling Drinking-Cups, of which the following is a specification.

My invention relates to improvements in bubbling drinking cups, and has among its salient objects,to provide a simple and practical fountain drinking cup with means therein for receiving the force of the water discharged into the cup from the supply pipe and directing it or checking itsdirection and force so that the main chamber of the cup must be first filled before the water can flow through the opening in its top, thereby equalizing the pressure and causing the water to be discharged from the cup in a uniform manner and with little or no variation and with no Spurting; to provide .a cup with a concaved upper surface, with non-squirt tubes extending from the concaved top through the body of the cup and discharging into the drain below, thereby making it impossible for children to squirt water from the side of the cup by placing their hands over the cup,'for the reason that the water is forced through the non-squirt tubes and escapes below into the drain; to provide a simple and inaccessible (except by a screw-driver) means for regulating the discharge of the water into the cup. 7

Other advantages will be apparent from the following description of one practical embodiment of my invention, shown for illustrative purposes in the accompanying.

sheet of drawings,in which Figure 1 is a vertical sectional elevation of a cup embodying my invention; and

Fig. 2 is a top plan View thereof.

Some features of the present invention are illustrated in my pending application, Serial No. 7 85,221, filed Aug. 18, 1913, and are now divided from that application. particularly to the concaved top with the non-squirt tubes leading therefrom through V the body of the cup to the drain below.

Referring now to the drawings in detail, the cup body comprises a lower portionl, and an upper portion 2, secured together, as

7 indicated. 7 The upper portion 2 is provided h a concaved top 3, with a central open I refer,

" proper size, and has leading therethrough an. inlet passageway. 7, which is enlarged at its upper end and then is continued in a series of small inlet ports, as 8- -8, discharging into the ma'inchamber ofthe cup above. 9 designatesa valve member screwed into the lower portion of the body, substantially in the manner indicated, with its lower end adapted to seat uponthe inlet opening 7 in a way to close the same,"'or partially close it,

asmay be desired, when said valve member is screwed downwardly. Said member is providedaround its upper'portion 'with a flange Or disk-like portion 10 which overlies the inlet ports 88,, so that the water discharged through them into the main chamber of the cup first strikes said member and its force is checked and the chamber must be filled before the water will-be forced out of the discharge opening 4: in the concaved top. The upper end ofsaid valve member is adapted, as at 11, to receive the end of a screw driver, with which it can be turned up or down, as desired, to regulate the flow of the water into the cup;

Thus the force of the water discharged into the cup chamber is checked by the member 10 and makes it necessary for the cup to be filled before the water is discharged through the discharge opening 4. This, in effect, constitutes a cushion for the water force from the supply pipe. Then again, the concaved top insures that there will be a thin sheet of water running over the top surface ofthe cup and over the sides thereof, keeping the cup top clean. I

I do not limit the invention tothe particular details here shown, for illustrative pur- 'poses, except as I maybe limited by the hereto appended claims, knowing that changes can be made therein without departing from the spirit of the invention.

I claim, V c i V 1. A bubbling cup comprising a globularshaped body having a concaved top with a discharge opening therein, oneor more non squirt tubes'from said concaved top through the body of said cup, means for attaching said cup to a source of water supply, with one or more inlet openings or ports into the interior of said cup, and an imperforate defiector member therein directly over said inlet openings, or ports, and against which in flowing water is discharged, whereby to make it necessary for said cup to be filled before water is discharged from the discharge opening in said concaved top.

2. A bubbling drinking cup of the character shown and described, comprising a body of globular form having a concaved top with central discharge opening therein, and adapted at its other end to be attached to a source of water supply, with one or more inlet ports into the interior of said cup, an imperforate deflector adjustably mounted within said cup directly over saidinlet ports and in alinement with said central discharge opening in said concaved top, said deflector being adapted at its upper end to be engaged by an instrument inserted through said central discharge opening for adjusting said deflector, and one or more non-squirt tubes from said concaved top through the body of said cup, whereby to provide a way of escape for the water when the hand is placed over the top of said cup.

3. A bubbling drinking cup of the character shown and described comprising a body Copies of this patent may be obtained for of globular form having a shallow concaved top with a central discharge opening therein, one or more non-squirt tubes extending through the body of said cup and communicating at their upper ends with the concaved surface thereof and at their lower ends discharging through the outside wall of the cup, said cup being adapted at its lower end to be connected with a source of water sup- P of said cup, and an imperforate buifer-like deflector member adj ustablydisposed within said cup directly above the inlet openings into the interior thereof, whereby the water discharged into the interior of said cup strikes said deflector, whereby the interior of the cup must be filled before water can be forced from the central discharge opening thereof, said deflector member being adapted at its lower end to cut off the supply of water to the interior 01": said cup, and being accessible only by means of an instrinnent through said central opening in said concaved top, substantially as described.
